Numerous existing formulas predicted the ultimate interfacial bond strength in concrete-filled steel tubes (CFST) between and concrete core without investigating whole response under push-out load. In this research, four models are proposed to predict behavior CFST including post-peak branch loading test based on 157 circular specimens 105 squared from literature. Two (one for one CFST) develop...

In this study, the mechanical properties of different CFST column shapes, including circular, rectangular, square, square with rounded corners, and triangular, are all analyzed compared using ANSYS R2 2021 software. Total deformation, equivalent stress in concrete steel, elastic strain characteristics various shapes also compared. axial load as well highest that columns can support. Comparing c...

Figure 3: Spiral-In and Spiral-Out raw images in a human brain (24cm x 24cm, a-c) and cylindrical phantom placed perpendicular to B0 (6cm x 6cm, d-f). The various TEs are a) Spiral-Out 18ms, b) Spiral-In 30ms, c) Spiral-In 42ms, d) Spiral-Out 7.4ms, e) SpiralIn 30ms and f) Spiral-In 52.6ms. Figure 1: R2* map of cylindrical phantom filled with tubes containing materials with varying R2* (arrow i...

FIG. 1. The wiring diagram of the microvoltmeter as it is used in pH measurements. The variable resistors should be of highest quality, and may be obtained from the General Radio Co. The tube bases should be removed and the cups at the bottoms of the tubes should be filled with paraffin. Special care should be taken in the construction of the switch in the grid lead of the sensitive tube as it ...
